      (#) Enable The ACMP interface clock using
          RCC_APBPeriphClockCmd(RCC_APB_PERIPH_ACMP, ENABLE).

      (#) Configure the positive and negative input pins of the analog
          comparator:
        (+) Enable the clock for the ACMP GPIO using the following function:
              RCC_AHBPeriphClockCmd(RCC_AHB_PERIPH_GPIO, ENABLE).
        (+) Configure these ACMP pins in analog mode using GPIO_Init() function.
        (+) Set these ACMP pins analog alternate functionin using
            GPIO_AnaAFConfig() function.

      (#) Configure the ACMP polarity, positive and negative input, filter
          and HYS using the ACMP_Init() function.

      (#) Activate the ACMP peripheral using ACMP_Cmd() function.

      (#) Get ACMP ready status using ACMP_GetReadyStatus() function.

      (#) Get ACMP compare result using ACMP_GetCompareResult() function.

      (#) ACMP interrupt configuration:
        (+) To activate the ACMP interrupt, use ACMP_IntCmd() functions.
        (+) Check on ACMP interrupt enable flags using the function
            ACMP_GetIntCmdStatus().
        (+) Check on ACMP interrupt occur flags using the function
            ACMP_GetIntFlagStatus().
        (+) Clear ACMP interrupt flags using the function ACMP_ClearIntFlag().
